The trial phase of spinal cord stimulation implantation for pain relief involves the temporary placement of nerve stimulators, which are small medical devices, in the patient’s body. The device creates nerve signals to interrupt the transmission of pain signals from the spine to the brain, providing effective pain relief. The sensation of pain is transformed into pins and needles or numbness instead. The patient can determine the level of stimulation for different times of the day or adjust the level to accommodate the activity being performed. The device can be controlled with something that is similar to a television remote control.
